Raw can be used to query raw bindings. Stick a -q switch in, and it queries things rather than sets them. The man pages for raw are quite good on this.

Off the top of my head (not having an ASM instance to hand), I don't think you can see a disk label and the physical device it's bound to uising any oracleasm command. There's querydisk and listdisk, but their output is not what you are after. However, the V$ASM_DISK view query-able from an ASM instance will map a PATH to a disk label, and I think that will give you what you want.
